IMPORTANT SAFETY INFORMATION

General Safety Warnings

WARNING Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible

conditions and situations that may occur. It must be understood by the operator that common sense

and caution are factors which cannot be built into this product, but must be supplied by the operator.

1. Work area safety

a. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b. Do not operate the Compressor in explosive

atmospheres, such as in the presence

of flammable liquids, gases or dust.

Compressor motors produce sparks

which may ignite the dust or fumes.

c. Keep children and bystanders away

from an operating compressor.

2. Electrical safety

a. Compressor plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with grounded

compressors. Standard plugs and matching

outlets will reduce risk of electric shock.
